Description

The SL-1800 features full Technics uncompromising direct drive performance in a simple, straightforward package.

The centre of this sleek, attractive unit is its highly accurate One Chip IC controlled servo drive motor.

This direct drive motor, which incorporates all of the design features of all Technics fine DD motors, is controlled by the unique BFG system which utilises the back electromotive force induced by the rotor in the stator field coils to monitor the platter speed.

The frequency generator in the SL-1800 uses the waveform obtained as its reference and it is compared with the standard calibration frequency from the reference oscillator.

In this way, a signal to correct the speed can be sent instantly whenever needed to change the motor drive current in order to maintain precise platter speed.

Arm Rest replacement for Technics SL 1800

Help! I need to know how to replace an armrest on my Technics SL-1800, the black portion was accidentally broken off. Anyone know how to do it? Do I have to take the turntable apart or can it be easily replaced? If anyone has a repair manual PDF that would be of great help! Thanks!

Armrest

Hi, I just bought a sl-1800 with the same problem. I found one on Ebay but it is listed as a SL-1200 part. The seller said it would work for the 1800. I just ordered one and have not received it yet. One site lised it for only $4.95 with free shipping. I thought it would be worth the small change.
Good luck!
